Georgia Tech students developed a computational tool to estimate risks from chemical vapors in enclosed areas such as tanker trucks. The project originated in a course on chemical equity that addressed exposure reduction in vulnerable communities. The course belongs to the university’s Vertically Integrated Projects program, which places students in extended research teams spanning multiple disciplines and semesters.
The group created a model that calculates buildup of hazardous vapors in confined spaces. Their results were published in ACS Chemical Health & Safety. One student said the effort strengthened her commitment to chemical equity and open-ended research, confirming plans for doctoral studies at Northwestern University.
The class responded to differences between controlled laboratory conditions and daily chemical handling. Faculty partnered with occupational health specialists to launch the course, drawing students from chemistry, biology, computer science and related fields. Guest speakers from journalism, law and policy also participated.
The model targets rapid exposure estimates after spills or open containers in limited spaces. Using benzene as an example, it forecasts concentration changes over minutes to hours and at different heights for standing or crouching individuals. Mentors noted gaps in existing models for transportation, agriculture and sanitation settings. The team aims to release a user-friendly application, illustrating the value of interdisciplinary education.
